It all depends on what type of fishing you will be doing bassbum on whether or not if you will even want a leader. If your using a jig/minnow set up you will not want a leader, If your trolling or drifing most people are suggesting now that you use flouro for the leaders which I am not sure I would trust the flouro yet but many of the anglers here do, Walleyhunter I think it was said that he uses 8lb test on his leaders when he trolls but fishes with 40lb PP as his main. your best bait for locating eyes mid summer is to troll spoons that match the forage if you have yellow perch in good amounts troll those patterns they have more fat in them then shad do and when they are available walleye prefer them vs shad and if shad are the main forage base troll your Silvers, Purples and Blues, Spring and fall Cotton Cordells Walleye divers are hard to beat, but DD Husky Jerks work well too, same with the Rapala Original Floaters if you can find a 5' shelf to troll in murky water with a semi decent chop. I hope this helps you out a little bit and dont confuse your exploring anymore then it already was.
The leader is really up to you what ever you feel comfortable with.
I am a die hard sportsman which Means I do it for the sport I do it as light as possible. My dream is to catch some spawning eyes on fly-fishing gear before I die I think a 6lb walleye on fly gear would be exhilarating.
